摘要: An apparatus and method for tracing memory access information of a user program while ensuring a normal operation of the user program. An access permission about a memory region may be set to trace the memory access information. An instruction of the user program encounters a page fault according to the set access permission. If the page fault occurs, memory access information is stored based on the page fault, and apparatus executes an instruction causing the page fault while in a supervisor mode.

摘要: A method of detection of erroneous memory usage is provided. The method includes starting a computer and executing a program and a monitoring tool to collect calls to a memory during execution of the program, detecting a call to the memory using the monitoring tool, extracting lines of code which request access to a memory address via the call to the memory, detecting a set of variables to which access is granted via the call to the memory, extracting, after execution of the predetermined program, the set of variables for each of the lines of code, detecting erroneous memory usage by matching the extracted lines of code with the set of variables, and determining the call as erroneous upon access being granted to the memory corresponding to the set of variables during execution of the predetermined program when access is not possible during the execution of the program.

摘要: An image sensor is wieldy used in many fields, including medical field and security device. Specifically, the image sensor is most widely used in digital camera and mobile phone. The digital camera and the mobile phone requires capture image of higher resolution and higher quality. However, a preview size of the mobile phone or digital camera requires a small size because of a display limitation. Therefore, a function of reducing an image size or magnifying a specific portion of the picture is essential in the image sensor. Accordingly, there is provided an image sensor with a scaler. The image sensor with the scaler can arbitrarily adjust a size of an image without any additional scaling chip.
